IMPROVEMENT IN WASHING-MACHINES.

Specification forming part of Letters Patent No. 119,244, datedSeptember 26, 1871.

. fication- Figure 1 being a view in perspective of the Washing-machine;Fig. 2, a longitudinal vertical section of the same; Fig. 3, view of apart detached.

Like letters designate corresponding parts in all of the figures.

My invention belongs to a class of washing-machines composed of arevolving cylinder or drum havin g rounds, preferably, or corrugationsaround its periphery, and turning in a nearly-concentric concave ofrounds or corrugations.

Let A represent the tub or box forming the water-reservoir, in which theworking parts are mounted; B, the revolving cylinder or drum, turned bya crank, a, or other means; and O, the concave. The cylinder-shaft ismounted in bearings b b, which have an adjustable movement up and downin grooves or ways of the sides of the tub or box, and are held atvarious heights by notches and a detent, c, or by holes anda hook, d,Fig. l, by which the distance of the cylinder from the concave below isadjusted.

My invention consists in the special features of construction andarrangement, as follows: In order to give the proper elasticity andyielding movement to theconcave C it is composed of two side pieces, ff, in which the transverse rounds g g are secured, and these side piecesslide freely up and down inside of the tub or box just inside of thesides thereof, and rest at their ends upon the elastic ends of twodouble springs, h h, which, respectively, extend across the ends of thebox or tub and rest on the bottom thereof. These springs are double,being fastened at the middle to the bottom of the box, so that both endsspring freely and separately and balance the weight of the two sides ofthe concave thereon. Thusthe concave rests at each end upon anA elasticyielding support, giving it every capability of adaptation to thevarious thicknesses of clothes between it and the cylinder, and by verysimple means. The springs are preferably made of wood. At the back ofthe machine the concave extends upward nearly to the top of the box, oras high as the center ofthe revolving cylinder. This upward extension z'of the concave is in a separate part, and is jointed to the main concaveby a spring-joint at the inner surface, as shown in Fig. 2, the springsl forming the joint being attached to both parts ofthe concave sidepieces. The back part of the extension is cut away at the bottom,leaving sufficient space m between it and the main concave below toallow the extension to yield backward and downward, and thereby separatefrom the revolving cylinder. This extension may be allowed to springforward close to the cylinder, so that it squeezes the water from theclothes as they ascend between it and the cylinder; and when the clothesare Washed and rinsed they may be run through the machine, the waterhaving been drawn oft', and this extension will serve as a wringer. Thesprings l Z may be made of steel, and any other construction orarrangement thereof may be employed. The front end of the tub or box Ais open at the top, as at n, down to a line lower than the center of thecylinder, leaving enough at the lower part closed to hold the requiredquantity of water. A shelf or table, p, is located at the bottom of theopening n, extending inward over the end of the concave, to rest theclothes upon and to prevent the slopping out of the water. It isinclined inward a little to conduct back into the tub or box all waterthat may spatter or drain upon it.

v What I claim as my invention, and desire to secure by Letters Patent,is-

The combination and arrangement of the concave C, elastic extension i,springs h h, and opening a in the front of the tub or box, constructedsubstantially as and for the purposes herein speciied.

Specification signed by me this 8th day of October, 1870.
